' IMPROVEMENT IN FIRE-PLACE STOVES.

Specification forming part of Letters Patent No. 152,854, dated July7,1874 application filed May 12, 1874.

To all whom it may concern:

Be it known that I, WILLIAM MAGILL, of Port Deposit, in the county ofCecil and State of Maryland, have invented a new and useful Improvementin Stoves; and I do hereby declare the following to be a full, clear,and eX- act description of the same, reference being had to theaccompanying drawings, in which- Figure 1 is a front elevation, showingmy improvement. Fig. 2 is a diagonal sectional elevation of the same.Fig. 3 is a sectional elevation on a medial line from front to rear.

This invention relates particularly to that class of stoves which areknown as parlor or lire-place heaters, though it is applicable to anyother class of stoves designed to warm the apartment in which the samemay be placed. Its object is to afford an increased supply of hot air towarm the apartment in which the stove may be placed, and thus remedy adefect in ordinary fire-place heaters. My invention consists inconstructing a stove with an open space or gallery immediately above thelire-pot or combustion-chamber, said gallery being open along its frontto the apartment in which the stove is placed, and connected with thefresh-air duct at the bottom of the stove by pipes, which may beadvantageously placed within the diving-fines, so that a continualcurrent of fresh air may be established through said pipes and gallery,the same being warmed in its passage and discharged into the surroundingatmosphere.

That others may fully understand my invention, I will particularlydescribe it.

A is the fire-pot or combustion-chamber of my stove. The draft may beintroduced at the bottom in the common way, or, as I prefer, at Vthetop, in the manner shown in my patent granted to me January 28, 1873.The products of combustion ascend through short ilucs B B to thesmoke-chamber C, whence they pass either directly into the escape-nue Dor through the diving-fines E to the base of the stove, whence theyescape into the back ilue F and into the flue D. So far as thiscirculation of the hot products of combustion is concerned thereisnothing peculiar in my invention; but I construct an open gallery orspace, Gr, immediately above the combustionchamber, and between it andthe smoke-chamber C surrounding the magazine H, if there is one, thusconstituting an open hot-air chamber communicating with the atmosphereof the apartment in which the stove stands.

This open space, however, would not of itself' create the requisitecirculation or ilow of air through it, and it is necessary t0 providefor that purpose inlet-pipes leading from points of lower temperaturethan exists within the gallery G. For this purpose I place theinletpipes I within the diving-fines E. These pipes I communicate attheir upper ends with the gallery G and their lower ends open below thebase of the stove, and may communicate there with the cold-air duct, ifone is used. The air passing through the pipes I becomes warmed by thehot products of combustion passing down through the diving-flue E beforeit enters the gallery G, and being heated still more within said gallerywill escape into the surrounding air, and thus distribute in theapartment wherein the stove stands a portion of the heat which otherwisewould be carried into the hot-air flue and carried to other parts of thebuilding. A flat nap-valve, J, closes the direct draft-opening betweenthe smokechamber C and ilue D, and an additional checkvalve, K, isplaced in the upright flue F.

Having described my invention, what I claim as new isl. In combination,the combustion-chamber A, connecting-fines B, smoke ue or chamber O, andintervening hot-air space or gallery G, opeuin g across the front of thestove and provided with cold-air inlets extending near to the bottom ofthe stove, or to such point as will permit ingress of cold air,substantially as and for the purpose set forth.

2. In combination with the hot-air space or gallery G, open across thefront of the stove, the inlet-pipes I located within the divin g-fluesE, as set forth.

VILLIAM MAGILL.
